My iphone SE is unable to make calls. It is saying "an update is required to use cellular data on this iphone".
The error started 2 days ago, before I updated to IOS 12.1, i have now updated to IOS 12.1 but it is still saying the message above and "no service" (I can connect to WiFI).
Spoke to Apple and they think it is an issue with my carrier. I have tried all ways of fixing it (reset network settings, removing and replacing SIM etc) but no luck.
Any help please? I cant currently use my 4G allowance which is very frustrating.
